|
|
|
26 -- OBJECTIVE:
|
|
|
27 -- Check that subprograms inherited from tagged derivations, which are
|
|
|
28 -- subsequently redefined for the derived type, are available to the
|
|
|
29 -- package defining the new class via view conversion. Check
|
|
|
30 -- that operations performed on objects using view conversion do not
|
|
|
31 -- affect the extended fields. Check that visible operations not masked
|
|
|
32 -- by the deriving package remain available to the client, and do not
|
|
|
33 -- affect the extended fields.
|
|
|
34 --
|
|
|
35 -- TEST DESCRIPTION:
|
|
|
36 -- This test declares a tagged type, with a constructor operation,
|
|
|
37 -- derives a type from that tagged type, and declares a constructor
|
|
|
38 -- operation which masks the inherited operation. It then tests
|
|
|
39 -- that the correct constructor is called, and that the extended
|
|
|
40 -- part of the derived type remains untouched as appropriate.
|
|
|
41 --
|
|
|
42 --
|
|
|
43 -- CHANGE HISTORY:
|
|
|
44 -- 06 Dec 94 SAIC ACVC 2.0
|
|
|
45 -- 19 Dec 94 SAIC Removed RM references from objective text.
|
|
|
46 -- 04 Jan 94 SAIC Fixed objective typo, removed dead code.
